DOVER —Onlookers flooded New York Street Saturday night, as firefighters from all over the area battled a blaze at an unoccupied multifamily home, which reportedly caught fire shortly after a vehicle caught on fire at the other end of the street.

According to Fire Assistant Chief Jim Ormond, a Jeep Wrangler was in flames in the area of 4 New York St. Saturday night, and while fire officials were still battling those flames, a structure fire was reported at 34 New York St.

Ormond could not say Saturday whether the two instances are related, and fire officials were still conducting interviews with area residents on Friday night as part of their investigation.

Almost simultaneously, a fire officials also responded to a rollover vehicle accident on Spaulding Turnpike, near Exit 6, in which two patients had been trapped inside a vehicle and had to be extricated.

"We don't normally get three accidents at a time," said Ormond.

The three-alarm fire drew response from multiple fire departments in the area. The fire at 34 New York St. was under control by 11:15 p.m., but Ormond said Saturday that fire officials will be staying at the scene throughout the night to ensure the fire does not reignite.

Ormond said that upon arrival to the home shortly after the structure fire was reported, firefighters encountered flames on the first- and second- stories of the building, and the fire was extending to the third floor.

The origin of the structure fire is not known at this time. Ormond noted that the building is "quite large."

New York Street resident Latoya Wallace, 26, said the building that caught fire had been vacant for several months.

"Thank god nobody lives there," she said, as she watched the flames and smoke coming out of the building.

Nicole Miller, a 32-year-old New York Street resident who lives across from 4 New York St., said she saw the Jeep engulfed in flames Saturday night.

"It was popping and exploding and the car alarm was going off," she said. "The flames were shooting straight up into the air. It was scary."

The siding of the home at 4 New York Street was visibly damaged Saturday night.

Ormond said that nobody was near the Jeep when emergency officials responded to the vehicle fire.

Miller said she has never seen the Jeep Wrangler in the New York Street area before. She said she saw the house on the other end of her street on fire within five minutes of the Jeep being in flames.

She said the firefighters "had just put out the truck (Jeep), and they ran across the street. They were running back and forth across the street."

Ormond said that as of 11:30 p.m., no firefighters were injured in Saturday's incident.

Fire departments from Dover, Durham, Rochester, Portsmouth, Newington, and South Berwick, Maine, as well as other areas.

"There's so many fire departments here, it's crazy," said Kelly McNeal, a 27-year-old Somersworth resident who heard about the fire from her friend before coming to the scene.

"It's quite scary," said McNeal.

Amanda Jones, 22, of Milton, had been driving on Route 108 and saw the smoke above the tree tops on New York Street.

It is not known at this time what time the two fires on New York Street, and the vehicle accident on the Spaulding Turnpike, were reported.
